LAWRENCE, Mass., June 17 /PRNewswire-FirstCall/ -- NxStage Medical, Inc. , a leading manufacturer of innovative dialysis products, today announced a 5-year distribution agreement in the United States between its subsidiary, Medisystems Corporation, and Gambro, pursuant to which Medisystems will supply blood tubing sets, including the ReadySet(R) and the Streamline(R) to Gambro. Gambro, in turn, will exclusively supply the bloodlines to certain customers for use with specific dialysis machines, subject to certain conditions.

Bloodlines are essential products used to deliver in-center dialysis treatments to patients with renal failure. This relationship builds upon NxStage's existing distribution relationships with long-standing partners Henry Schein, Inc. and B.Braun Medical, and will help to ensure that Medisystems' world class blood tubing set products are accessible to patients across the United States.

"We are pleased to offer Medisystems' bloodlines as part of our product portfolio for chronic dialysis," said Nick Mendez, President of Gambro Americas. "We believe Medisystems' products deliver leading quality, performance, and customer satisfaction. The Medisystems product line, particularly the Streamline technology, complements the unique value Gambro delivers to dialysis centers and patients with such novel technology as is incorporated into for instance Gambro's new Revaclear dialyzers. We look forward to a productive relationship with Medisystems."

"Gambro is clearly a world leader in hemodialysis technology and distribution," stated Jeffrey H. Burbank, Chief Executive Officer of NxStage Medical. "We believe the union of our innovation and product quality with Gambro's complementary technologies and distribution capabilities will further strengthen both companies' presence in the in-center dialysis products market."

Medisystems' latest generation blood tubing set is the Streamline. Streamline features an efficient and airless design intended to improve clinical and economic performance. Streamline is designed to reduce dialysate flow, dialyzer size, treatment time, minimize heparin and waste, and optimize dose delivery, as measured in Kt/V. Streamline also includes Medisystems' patented LockSite(R) needleless access ports, which eliminate the need for sharp needles or costlier guarded needles to be used with the tubing set during dialysis.
